NOAA Ocean Acidification Program monitoring data collected from the North Atlantic continental shelf in October-November 2019. Water samples from three depths at select stations were analyzed for dissolved inorganic carbon, pH, total alkalinity, and nutrients. These measurements support research on the adverse effects of ocean acidification on calcifying organisms and species of commercial interest.
Use Cases
- Monitoring short- and long-term coastal ocean acidification trends based on inorganic carbon measurements.
- Studying the impact of reduced pH on calcifying organisms like corals and oysters based on water chemistry data.
- Analyzing nutrient concentrations alongside carbon chemistry to understand broader ecosystem dynamics.
- Modeling carbon chemistry changes in specific regions like the Gulf of Maine and Georges Bank.
Strengths
- Data collected at three depths (surface, mid-depth, near bottom) for vertical profile analysis.
- Samples analyzed by authoritative labs (AOML and University of Maine) for key parameters.
- Cruise provides a focused temporal snapshot from October 15 to November 1, 2019.
Limitations
- Row count is unknown, which may limit suitability assessment.
- Column-level documentation is absent; field semantics must be inferred after download.
- Data may reflect geographic bias inherent to the specific cruise track in the North Atlantic.
